Use the scripts and screenshots below to configure a Kerberized cluster in minutes.
Kerberos is the foundation of securing your Apache Hadoop cluster. With Kerberos enabled, user authentication is required. Once users are authenticated, you can use projects like Apache Sentry (incubating) for role-based access control via GRANT/REVOKE statements.
Taming the three-headed dog that guards the gates of Hades is challenging, so Cloudera has put significant effort into making this process easier in Hadoop-based enterprise data hubs.
Set up a CDH-based Hadoop cluster in less than an hour using VirtualBox and Cloudera Manager.

I wanted to get familiar with the big data world, and decided to test Hadoop. Initially, I used Cloudera’s pre-built virtual machine with its full Apache Hadoop suite pre-configured (called Cloudera QuickStart VM),
The Cloudera QuickStart VM is an important platform for learning any Hadoop-related curriculum.
In the Fall 2013 semester, more than 30 NYU graduate students completed the Real-time and Big Data Analytics course at the NYU Courant Institute of Mathematical Sciences, for which I served as instructor.
In this introductory analytics course, students learn the architectures of the Apache Hadoop storage and compute systems (HDFS and MapReduce respectively).
One of the common questions I get from students and developers in my classes relates to IDEs and MapReduce: How do you create a MapReduce project in Eclipse and then debug it?
To answer that question, I have created a screencast showing you how, using Cloudera’s QuickStart VM. The QuickStart VM helps developers get started writing MapReduce code without having to worry about software installs and configuration. Everything is installed and ready to go.
OSCON 2013 is already receding in the rear-view mirror, but we had a great time. Cloudera’s sessions were very well attended — with Tom Wheeler taking the prize (well over 200 attendees for his “Introduction to Apache Hadoop” tutorial) — but best of all was the opportunity to meet and mingle with people in the broader open source community. If you visited us at Booth 420, we hope you will now download and install the QuickStart VM after seeing it in our demo,
